Nice concept and game, although I am unsure on the main objective and the usage of 'Enter' does not work properly, as I think you know already! I think the shops should not re-roll prices so that it is not a very large exploit: as in you could get infinite money without even moving the rocket ship. There should also be a stock limit, it just gives a greater incentive to move around and explore! But I enjoyed the game and its concept a lot!
